UNITED STATES PATENT CIRCULAR-COMBING MACHINE.

Application filed May 23,

This invention relates to the type of wool comb known as the Noble.

The principal objects of the invention are to modify the ordinary Noblecomb in such a way as to increase thefineness and purity of the productdelivered from the circles and also to provide a novel method of drivingthe new element which is of a flexible nature.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings in which Fig. 1 is adiagrammatic plan of a horizontal circular comb of the Noble type with apreferred embodiment of this invention applied thereto and illustratingonly a part of the outer circle;

Fig. 2 is an enlarged sectional view on 2 the line 2-2 of Fig. 1 showingthe features of this invention more fully; and

Fig. 3 is a plan on enlarged scale of part of the arc of one of thesmall circles showing the way in which the fibres lie thereon afterbeing pulled out by contact with the large circle.

It will not be necessary to describe the operation of the Noble comb asthis comb has all the features thereof and they work in the same way. Ihave shown the outer circle 10 provided with the usual pins and thesmall circles 11 also'provided with their usual pins; also thedrawing-off rollers 12 and 13 in their usual position and leathers 14operating in the ordinary way. These features of the Noble comb are notdisturbed in any way.

Within each of the small circles I provide a bracket 15 on the steam box19 and in it place an inclined shaft 16 which is driven from the circle.On this shaft is a brush body 20 which has a conical surface 21 aroundit provided with tufts of brush bris tles 22.

Although in Fig. l, on account of the fact that it is a sectional View;the bristles on the opposite edges of the brush body 20 project at rightangles to each other, the brush itself is conical in shape. The bristlesare cut off flat to form opposite conical surfaces at their ends.Therefore those bristles which come into contact with the pins 23 on thecircle 11 project into the spaces between these pins in a directionexactly parallel with them. For this reason thebrush will be driven bythe circle which is mounted on 1927. Serial No. 193,485.

ball bearings 24 on a stationary circular frame or support 25. r

It will be seenthat thisis a flexible-driving means and is, in a sense,positive, because under ordinary circumstances the tips of the bristleson the brush and the pins travel at the same speed. However, it preventsinjury to the fiber'that might result from an absolutely positive drive.On the brush is placed a circular flange 26, preferably integral'withthe brush frame, which is of metal. In this flange are located one ormore rows of staggered pins27, parallel with the bristles, which engagewith the outer rows of pins on the circle and draw the fibres around thepins and remove the nibs so that a finer, cleaner and more valuablesliver will be delivered to the drawingoff rollers 12. Different brusheswith finer or coarser placed pins may be substituted as required fordilferent wool.

Of course, the drawing-01f rollers 13 per form their usual functiontaking the sliver from the large circle and passing it between theleather and through the rollers 12 and from there to the; calenderrollers and can, generally used, but not shown in these drawings.

This constitutes an inexpensive addition to this machine and results inthe production of a better product Which can be sold at a higher price.It involves no parts that are in the way when it is desired to changethe circle as the brush bristles ofier no important resistance. It willbe understood that the other small circle is operated in the same wayand that the large circle can be a so. 1

The sliver is dabbed or pressed into pins of both circles in the usualway at the point where the periphery of a. small circle almost touchesthe interior side of the larger circle. The fibres retained among thepins of the small circle are drawn away from the large circle and arecombed. The part of the sliver which lies between the two circles is notcombed until it reaches the brush. The drawing-oft rollers draw thesliver through the brush and pins 27, thus combing nibs and vegetablematter from the part of the sliver that lies between the small and largecircles. This gives a better product on account of being free from nibs.

, Although I have illustrated and described only one form of theinvention I am aware of the fact that modifications can be made thereinby any person skilled in the art without departing from the scope of thelnven tion as expressed in the claims.

Therefore,1 donotwish to be limited to the details of constructionherein disclosed, but what I do claim is 1. The combination with thelarge and small circles of a horizontal circular combing machine, of arotary brush in position for the bristles thereof to enter between thepins of a small circle to rotate the brush, andaseries of pins carriedby 'thebrush for cooperating with the outer rows of pins on the smallcircle.

2 The combination with a freely rotatable horizontal pin circle, aninclined shaft above it, a conical brush body fixedon said shaft at anangle to the horizontal, a circle of bristles on the body, so locatedthat at the bottom of the brush body the bristles; are in verticalposition and project inamong the pins otsaid circle to be driven by it.

3. In a combing machine, the combination with a rotatable circle ofpins, means for rowith a horizontal pin ClIClB freely rotatable on itsaxis, of means for removing 'nibs therefrom comprising aconical brush,the

brush beingfrotatable on a central axis inclin'ed to a degreeverticalposition asithey'pass their lowest point and penetrate into thesets of, pins on,

the circle.
